I do not have experience with that set up.
My general comment about parking brakes with ANY vehicle with 4 wheel disc brakes is they suck.
At best you will be marginally able to hold the car with full pads.
It also depends on the compound of the pads. Sometimes hard pads are better. Sometimes soft.
Generally speaking in my experience, foot operated control levers are better then the hand operated.
The Panteras system would rank along with the worst designed systems, not the best.
Ask Mario. He'll know the most about his system.
